Owing to the fact that thepitch is conmeans for engagement with the barrel B or other vesfinedwithin the barrel, which is of wood and a poor sel, said meansconsisting in the present case of a conductor of heat, the pitch coolsbut slowly and flanged or extended shoulder a from which projects a 80therefore the rolling or movement of the barrels must tube (1 arrangedto extend a distance into the vessel, continue for some time. This delayin the cooling of this tube in the device shown being closed at one endthe pitch in each barrel is a serious inconvenience, as and providedwith a series of perforations. The tube it necessitates either a muchlarger machine for rolling a is made of such a diameter that it may beconvenor a larger rolling space and more men when the bariently insertedin the opening in the vessel, as for ex- 85 rels are rolled by hand inorder that the pitching apample, into the bung hole oi the barrel, asshown in paratus may proceed continuously.

The headA is ment is not always successful in removing all contamihollow, andhas a discharge outlet, as indicated at a 40 nations. provided withmeans for closing it and for opening it 95 The principal object of myinvention is to avoid quickly, such means consisting in the presentexamthese disadvantages, which are well known to those ple, of a gatevalve (1 operated by its handle 11*. skilled in the art and hence havebeen but briefly set Suitable means is provided for creating a suctionin forth above. the head A so that the vapors and smoke may be drawnWith this general object in view, and some others from the vessel anddischarged through the discharge 100 which will be obvious from thedescription hereinoutlet a This suction creating means connected withafter, my improved apparatus is arranged to carry out the head A,consists, in the present example, of a jet a process of pitching barrelswhich consists in first device and more particularly of a jet devicearranged applying a coating of pitch to the interior of the barrels tooperate with compressed In the embodiment and then exhausting the heatedair and vapors from of my invention shown in the drawings, this jetdevice 1 the barrel and admitting cooler air, as for example, consistsof a jet tube O arranged to discharge upward the outside air, to theinterior of the barrel, while or in a direction away from the barrel Band toward maintaining in the barrel a pressure below that of the thedischarge outlet a The jet tube 0 is provided incoming air which thusexpands as it enters the barrel with fluid under pressure from anysuitable source, as and thus assists in cooling the coating. l r t forexample, by means of a flexible conductor such as the hose 0 which isconnected with the jet tube 0 by means of a pipe 0 passing through thewall of the head A. The hose 0 is intended to be supplied with fluidunder pressure, as for example, compressed air from any suitable sourcenot shown. A valve C is placed at any convenient point in order tocontrol the supply of air or the like to the jet tube.

To the head A is connected a gage D by which the pressure or vacuum inthe head A may be ascertained Between the gage D and the head A isplaced a cock D whereby the communication between the head and the gagemay be cut off. The head A is mounted in such a manner that it may befirmly pressed against the barrel or other vessel and removed therefrom.In the example shown, the head A is mounted on the end of a bar Elongitudinally movable in a framework F, the bar E being provided withsuitable mechanisms for moving it longitudinally, as for example, bysupplying the bar E with a rack E engaged by a toothed segment G mountedon a lever G fulcrumed at G upon the frame Work, the free end of thelever G serving as an operating handle.

The frame-work F of the apparatus, in the preferred embodiment of myinvention, comprises a base F upon which the barrel B may be mountedupon suitable chock-blocks as indicated at F The tap-hole of the barrelB is shown at b.

In carrying out my process by the aid of the apparatus described thebarrel is first supplied with an interior coating of pitch in the usualway, as for example, by pouring the heated pitch at a temperature ofabout 400 to 425 Fahr. into the barrel, through the bung-hole, thetap-hole being plugged. The barrel is quickly rolled about and alsooscillated end ways sufliciently to bring the hot pitch into contactwith every part of the inside of the barrel. Then the latter is quicklyplaced upon the blocks F, with its bung-hole upward, the head A at thistime being elevated so as to be out of the way, by pulling down thelever G. As soon as the barrel is in place, upon the blocks F the head Ais rapidly depressed by releasing the lever G, whereupon the head A willdescend by its own weight, or its movement may be hastened by pushingupward on the lever G The tube a enters the bung-hole of the barrel andthe packing device a" comes into contact with the outside of the barrel.By pressing upward on the lever G, the said packing device a is firmlycompressed between the shoulder a and the barrel, thus making anair-tight or substantially air-tight connection between the head andbarrel. The plug being removed from the tap-hole of the barrel, thecompressed air is turned into the jet tube by opening the valve G thedischarge outlet a also being opened by opening its gate valve a Theescape of the compressed air upward through the jet tube 0 and outwardthrough the discharge outlet a causes a suction on the well knownprinciple of an injector and thus exhausts the vapors, smoke and heatedair from the interior of the barrel and discharges the same through thedischarge outlet u At this time, the cooler air from the outside rushesthrough the tap-hole into the barrel, but as the area of this opening isrestricted compared with the discharge capacity of the jet-device, therestricted tap-hole acts as an expansion valve and the incoming airexpands slightly as it enters the barrel. The immediate removal of thevapors and smoke and heated air, and the rapid cooling of the softpitch. The continued action of the jet-device causes a flow of thecooler air from the outside into the barrel through the tap-hole andoutward through the discharge outlet a so that the said air iscontinuously removed as rapidly as it becomes warmed by the heat whichit abstracts from the coating.

The gage D, may be put in communication with the head A at any time byopening the cock D in order to measure the vacuum which is beingproduced by the jet-device.

My improved apparatus has an additional feature which adds to its value,as will now be explained. Some of the experts in this art prefer tosubmit the interior of the barrel to a pressure such as the pressure ofcompressed air after the pitch coating is in place and before the samehas been entirely hardened. With my apparatus, this can be done atanytime desired, by merely closing the gatevalve a and the tap-hole b ofthe barrel, whereupon the jet-device ceases to function as aninjectorand the compressed air is confined in the head A and barrel Buntil the pressure in the latter is equal to that of the supply ofcompressed air. The gage D'serves to indicate and thus allow the controlof this pressure.

When the treatment of the barrel is completed, the lever G may be pulleddown thus lifting the head A and its tube a clear of the barrel,whereupon the latter may be removed from the blocks and the apparatus isready to receive the next barrel to be treated.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. In an apparatus of the class described, the combination with a headhaving a discharge outlet, 01: a jetxlevice connected to the head, andmeans for connecting the head to the vessel to he treated.

2. In an apparatus of the class described, the combina' tion. with ahead, means for pressing the headagainst the side of the vessel to betreated, and a packing device between said head and said vessel, ofmeans for creating a suction within the head.

In an apparatus, of the class described, the combination, with a headhaving a discharge outlet, of a jet-device connected to the head, avalve for closing the discharge outlet, and means for putting theinterior or the head in communication with the interior of the vessel tohe treated.

4. In an apparatus of the class described, the combination, with a headhaving a discharge outlet, of a jet-tube within said head, means forsupplying fluid under pressure to the jet tube, and means for puttingthe interior of the head in communication with the interior of thevessel to be treated. I
